In Regard to Research Questions and Hypotheses, a High-Quality Research

In regard to research questions and hypotheses, a high-quality research study will:

A) articulate only research questions, not hypotheses, so as not to constrain the possible findings.
B) articulate only hypotheses, not research questions, in order to preserve the scientific rigor of the investigation.
C) focus only on those questions that can support the correctness of current hypotheses or theoretical positions.
D) articulate either research questions or hypotheses depending on the nature of the study.
